[1000mp] MK-V Band Data Problem

[Smith, Dave]

Hello folks,

I'm new to the list and maybe this has been asked before.

Does anyone have any experience in trouble shooting or repairing the =
band data output? I've ordered a service manual (CD) from Yaesu this =
morning. I get zero output on pins A, B and D but a constant 3.8 volts =
on the C lead. It doesn't matter which band the radio is on... none of =
the leads change state.=20

Any input from the group would be appreciated.
